The Brooks Glycerin GTS delivers plush cushioning with dependable stability. DNA TUNED technology uses dual-cell foam to create soft heel landings and responsive forefoot push-offs, whilst GuideRails® support keeps your body moving in its natural alignment. Instead of fighting overpronation, the system works quietly in the background, guiding excess movement at your feet, knees and hips. The engineered knit upper wraps your foot in breathable comfort that flexes as you move. Premium cushioning for runners who need support but won't sacrifice softness.
